  The prediction model of FE bridge structure and FE-SEA hybrid bridge structure is established by using a frequency-dividing strategy.The frequency domain and characteristics of the vibration and structural noise of the U-beam within the 1.25Hz~250Hz frequency range,when subjected to a vertical wheel-rail interaction force,were analyzed.

随着城市规模扩大和居民出行需求增加,传统的城市轨道交通站站停方案已无法满足乘客多样化的出行需求,快慢车方案得到越来越多的研究与实践。针对城市轨道交通快慢车模式运输组织问题,在分析影响快慢车停站方案因素的基础上,以乘客时间节省和企业运营成本节省最大化为优化目标,建立0-1整数规划模型,将所建模型运用到实际轨道交通线路中,并设计遗传算法求解模型。
